The author explains how they built a compute platform capable of launching millions of sandboxes per second in constant time, focusing on decoupled scheduling and capacity aggregation using Cassandra and S3.

This project turns an ESP32-S3 development board into a USB drive that appears to contain every possible file, inspired by the Library of Babel. It's a fun hack that generates arbitrary file contents based on path names using MTP protocol.

Streambed is an open-source CDC engine that streams Postgres WAL changes to Iceberg tables on S3, with a built-in query server using DuckDB that speaks the Postgres wire protocol.

A tweet discusses the idea of building a transactional database with infinite throughput using S3-like object storage and content-addressing, where blocks are written in parallel and the root hash is updated periodically.

Almog Gavra announces that a performance optimization using HEAD requests instead of LIST calls has been deployed at Dropbox, reducing SlateDB startup time by 60x.
